The funny part being that they write it as if the ideas are preposterous. Putting religion at the very basis of the operation of the universe is one hell of a drug.
EDIT: Already made it a comment, but I feel it's important before people get that idea that these people are necessarily our enemies.
People write/read takes like this and come to radically different conclusions due to their different base axioms of human experience. For the target readership of catholicculture.org, they are ones that are trying to understand the universe, with the base assumption being the existence of a Christian god. Many an apologetic has attempted to synthesize the real observable world with a just, righteous god. Regardless of their flawed logics, they are at least interested in taking a holistic approach to the human experience rather than an individual, capitalist, exploitative experience. As someone who as a child dove into the catholic theological worldview, desperate for meaning in this clearly meaning deprived society, these people can be radicalized, and are capable of changing their basis of thought. It takes real effort and patience, but they are much more likely to be a devoted comrade to the human liberatory unification experience than a bourgeois hedonistic individualist, who only cares for themselves and the people closest to them, who would rather not ponder their experience let alone the collective human experience, but rather live their own lives in pursuit of illusory happiness in isolation.
Why should the limits of human intelligence determine whether something is a physical process? Why would we assume that some artificial or alien intelligence of arbitrary complexity would never be able to understand it? The question I would ask is whether it would be possible to take a physical description of the system, and create another system with the same physical description that does not have "consciousness". If there isn't evidence of this, or of a mechanism where it would be possible, I don't see why we should say that consciousness is anything outside of materialism.
